  • Epidemiological survey is an important means for the prevention and control of infectious diseases. Due to the particularity of the epidemic survey, 1) epidemiological survey in epidemic prevention and control has a wide range of people involved, a large number of data collected, strong requirements for information disclosure and high timeliness of data processing; 2) the epidemiological survey data need to be disclosed at different institutions and the use of data has different permission requirements. As a result, it easily causes personal privacy disclosure. Therefore, traditional access control technologies are unsuitable for the privacy protection of epidemiological survey data. In view of these situations, we propose a black box-assisted fine-grained hierarchical access control scheme for epidemiological survey data. Firstly, a black box-assisted multi-attribute authority management mechanism without a trusted center is established to avoid authority deception. Meanwhile, the establishment of a master key-free system not only reduces the storage load but also prevents the risk of master key disclosure. Secondly, a sensitivity classification method is proposed according to the confidentiality degree of the institution to which the data belong and the importance of the data properties to set fine-grained access permission. Thirdly, a hierarchical authorization algorithm combined with data sensitivity and hierarchical attribute-based encryption (ABE) technology is proposed to achieve hierarchical access control of epidemiological survey data. Efficiency analysis and experiments show that the scheme meets the security requirements of privacy protection and key management in epidemiological survey.

  • In this study, we proposed the FRAD concept model of authority data schema for author, organization and journal titles included in the academic papers. Academic information includes author names, affiliations, publishers, journals and conferences. They are used as access points, and there are multiple relationships among these entities. It is expected that the use of authority data for academic information based on FRAD conceptual model could improve more accurate retrieval of information, systematic management of academic information, and various forms of knowledge representation. In this study, our entity-relationship authority data will be linked to the document, and included the several properties and relationship to identify the object.

  • Recently, with the development of IT technology, authentication methods of users using cloud services have been diversified. However, research on providing authentication information of a user using a cloud service securely according to authority has not been make until now. In this paper, we propose a key establishment protocol which can perform split authentication using secret key and access control key according to the role authority of user in Intra cloud environment. The proposed protocol generates the access control key and secret key of the user by using the attributes of the user and the generated random number($t_1$, $t_2$), and classifies the roles according to the user's authority after generating the key. Unnecessary operation processes can be reduced. As a result of the performance evaluation, the proposed protocol guarantees the security against various type of attacks that may occur in the cloud environment because the user is authenticated by dividing the access control key and secret key. The size of the ciphertext used to establish the key could be reduced by ${\sum}+1$ more than the existing protocol.

  • As the bibliographic environment has been evolved towards linked data and semantic web, revision of KCR5 based on RDA is also in progress in Korea. Even authorized access points play an important role in identification and linkage between resources in the evolving bibliographic environment. However, the original RDA applied by KCR5 does not provide authorized access points for all entities. Based on the analysis of the authorized access point of manifestation in RDA 2020, this research identified properties and proposed a linking structure of the authorized access point that can be applied to the revision of KCR5. An authorized access point for manifestation is an access point that considers both intellectual and physical aspects, and can be the foundation for linking and identifying actual resources. The proposed structure is expected to be a linking structure for authority record optimized to the current bibliographic environment, which can be helpful in the practical application of the authorized access point for manifestation.

  • This article is a preliminary analysis for the study on the MARC formats for authorities. It tries to analyze the elements of the authority record. based on GARE, Guidelines for authority and reference entries, prepared by IFLA, from the Korean perspective. Its analysis follows the general structure of GARE, dividing the records into authority entry, reference entry, and general explanatory entry, and suggests and recommends the Korean examples applying the Guidelines. It also recommends that, for the Korean practice for the authority record to be firmly established, first of all, it is necessary to improve the infrastructure for the bibliographic control, including the completion of the rules for the selection of the access points or the headings and for their structure.

  • This paper provides suggestions for analyzing Cultural Objects Name Authority(CONA) developed by the Getty Trust and applying CONA to Functional Requirements for Subject Authority Data(FRSAD). CONA is linked with the other Getty controlled vocabularies such as AAT, ULAN, and TGN, and can be linked with the library controlled vocabularies, such as LCSH. However, CONA has differences with library models since CONA is based on the art museum or art gallery. Therefore, we need to consider it when we link CONA to library standard models. The results discussed in this study have implications for analyzing CONA which provides access for cultural objects and applying it to the FRSAD, the subject authority model in library fields.

  • Archival authority records support users in accessing and understanding archival information. The creator of the archives, on the other hand, is also the creator of other informative materials, including published products, and the users want to access information in a seamless manner. Moreover, the authority record has common attributes with the authority records for bibliographic control as well as its distinctive characteristics. Therefore, this research aims to link legacy authority records for constructing and expanding archival authority records and provide the expanded archival records to the Web environment, including Wikipedia, for data sharing. Finally, some issues and suggestions for further research based on the findings that resulted from experimental linking and sharing are discussed.

  • Name authority control is important for not only library catalogers but also end users, since it provides uniform access points. The national libraries in Japan and the United States have constructed and controlled authority records for writers from early days, and have provided them on the web sites. The purposes of this study are to extract common fields and differences in Japanese writer's name authority records of the U.S. and Japan, and to propose the ways of desirable description of authority records in Korea. Several suggestions of building authority records in National Library of Korea such as open to the pubic of authority records, provision of various forms of authority files, suggestion of the ways of writing the names of foreign writers, and the links between the authority records and library catalogs for retrieval are proposed.

  • This study is intended to build a cross-reference system as syndetic device to provide bibliographic relations and to collocate variant access points through references, by developing a reference record format. To this end, the method of this study are as follows: First, the roles of references, which have long been used in traditional records, have been reviewed. Second, ways in which references are depicted not only by current cataloging rules but also by authority control systems are examined. Major characteristics of the reference record are summarized as fellows: 1) If variations either of an author name or of a title are made, or any related works are published, only a single reference record is created. This record uses existing authority records, and instead of adopting authority headings, it will expand the function of the explanatory reference as well as newly implementing a relational reference which can later be used as a reference record. 2) All the variations of identical personal or group names and of lilies are dealt as one access point. In place of current 'see' and 'see also' references, not drawing lines between authority heading(1XX field), 'see'(4XX field) and 'see also' reference(5XX field), all forms of names will be simply applied to record field '1XX'. 3) Any form of data elements, which are used as access points, will be described in '1XX' which has equal value. When a need arises to explain relationships between various access points, it can be met by applying the general explanation reference-name(666 field). Similarly, when there is a need to articulate bibliographic relationships between related works, they will be suggested through the title and relational reference. 4) The title and relational reference regulates related terms that each relation type contains its field, according to each relational type, by reclassifying entire fields in order to provide direct bibliographic relation types on reference records. 5) Pointers which are connected to each access point present reference control numbers.
